• The meters Enerlux S of the category of measuring
working means and are meant for metering the electrical
energy, active and reactive, for domestic consumers and firms
using multi tarrif systems for billing the electrical energy in low
voltage single phase networks.
The meters have he possibility of consumer connecting /
disconnecting and can be equipped with a PLC modem.
